A method for electromagnetic radiation source identification is proposed. The spatial characteristic of a radiation source is taken as the unique parameter for support vector machines (SVMs) to identify. First, the location of radiation source is determined by the triangulation method, and then its spatial characteristic is collected by a band receiver array with simulation, which removes the limit...
This paper aims at resolving the visual simulation of electro-magnetic environment. It would build a set of parallel system from the perspective of EMC. The system works on the basis of C/S structure, and it has achieved beautiful interface and easy operation. It also adopts the parallel computing method for multiple child nodes and the acceleration algorithm of ray tracing. So the system could successfully...
A new terrain meshing method based on the ray-tracing algorithm is presented. In the propagation model, most of the transmission paths are focused in the area that between the transmitters and receivers. The main idea is to mesh the area containing both the transmitters and receivers into fine triangles while the rest area into larger triangles. The processing time of this developed method is half...
This paper constructed a whole frame of parallel computing and simulation system in complex electromagnetic environment based on file division idea to improve the compute speed of electromagnetic simulation in complex electromagnetic environment. The system was divided into four modules, client, sever, compute node and database. Compared with other simulation software, this system not only provided...
As for the complex electromagnetic environment simulation, this paper propose a parallel computing system based on file segment, this system offers the developer a flexible interface. The paper describes the database design in detail, analysis the performance of the database, therefore offers a base for the complex environment simulation.
A single chip receiver based on super-regeneration incorporates an on-chip slot antenna and digital received data synchronization. A capacitively-loaded standing-wave resonator improves energy efficiency. An all-digital PLL timing scheme synchronizes the received data clock. The prototype 5 GHz receiver, implemented in 0.13 mum CMOS, achieves a data rate of up to 1.2 Mb/s, dissipates 6.6 mW from a...
